A herniated disk, sometimes (incorrectly) called a slipped disk, is a common cause of severe back pain and sciatica. A disk in the lumbar area becomes herniated when it ruptures or thins out, and degenerates to the point that the gel within the disk (the nucleus pulposus) pushes outward.
Stretching and strengthening exercises that target the muscles of the lower back, abdomen, and thighs can help reduce the symptoms of sciatica. 1  A few beneficial exercises to help decrease pain associated with sciatica include: 2  Piriformis Muscle Stretches. 3  Low Back Stretches. 4  Hamstring Stretches. 5  Core Strengthening.
